Flow-increasing propeller for water lines

ABSTRACT

A power-driven screw propeller is operatively mounted in a conduit, a drain tile for example. An outboard motor is brought into play and is supportively installed at the bottom of an earth-embedded pit and is accessible by way of a covered manhole at the top of the pit. A boxlike well is built within the bottom part of the pit and the drain tile is passed through openings provided therefore in the pit and well. The usual self-contained transom brackets are hung from a horizontal brace. The conduit is provided with an entrance hole for the bladed propeller and a caplike plate covers the hole and is attached to and carried by the insertable and removable outboard motor.

Jacobson ABSTRACT: A power-driven screw propeller is operatively mounted in a conduit, a drain tile for example. An outboard motor is brought into play and is supportively installed at the bottom of an earth-embedded pit and is accessible by way ofa covered manhole at the top of the pit. A boxlike well is built within the bottom part of the pit and the drain tile is passed through openings provided therefore in the pit and well. The usual self-contained transom brackets are hung from a horizontal brace. The conduit is provided with an entrance hole for the bladed propeller and a caplike plate covers the hole and is attached to and carried by the insertable and removable outboard motor.

More specifically, the concept has to do with a feasible and acceptably practical manner of utilizing a well-known-type outboard motor and cooperatively associating the same with a boxlike well. This well has openings in opposed walls which are aligned with similar openings in the pit walls for passage of longitudinally spaced coacting portions of the drain tile or pipe. A brace is provided within the confines of the well and serves to accommodatingly suspend the outboard motor at a level and in a position that the propeller at the bottom thereof is operatively mounted in the conduit or passage of the stated tile.

Briefly, the earth-embedded pit embodies brick or equivalent walls and has a top wall which in turn is provided with a manhole, said manhole being provided with an accessible readily removable and applicable lid-type cover. When the manhole cover is removed, access can then be had to the open top of the wooden or equivalent boxlike well. This well is appropriately erected in the bottom portion of the pit and is such in size that it serves to accommodate the coacting component parts of the intact insertable and removable outboard motor. A horizontal brace is installed in the upper open portion of the box or well to accommodatingly support the transom brackets carried, as usual, by a reinforcing sleeve at the upper end portion of the shaft housing of the outboard motor. For best results the top quadrant of the drain tile is cut out to provide an opening through which the lower propeller-equipped part of the outboard motor is inserted. This lower portion is provided with an arcuate cap to close the hole and the cap constitutes an adapter and is carried as a complemental part ofthe bodily insertable and removable outboard motor.

More explicitly, the adapter hole in the tile or conduit is provided with diametrically opposite outstanding ledgelike flanges to accommodate holddown flanges provided on. prescribed marginal edge portions of the caplike adapter.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. I is a view appearing in section and elevation showing the earth or ground, the embedded brick or equivalent pit and manhole cover, the built in box, the apertured conduit or tile, the insertable and removable outboard motor, and how it functions as a flow-boosting and increasing propeller.

FIG. 2 is a view at right angles to FIG. 1; and

FIG. 3 is a horizontal section with parts in elevation taken on the plane of the section line 3-3 of FIG. 1.

With reference first to FIG. 1 the pit, generally stated, is denoted by the numeral 6 and is made of bricks or the like and is embedded in the ground or earth 8. The opposed brick walls 10 are provided with openings 12 to permit passage of coacting portions 14 of the conduit or drain tile 16. The top wall 18 is provided with a manhole 20 covered by the lid or manhole cover 22. The upper quadrant or sector of the conduit or drain tile 16 is provided with a generally rectangular hole 24 which is capable of accommodating the attachable and detachable arcuate plate which is here referred to as an adapter 26. This adapter is carried by the depending shaft housing 28 of the insertable and removable outboard motor 30. A suitable gasket is provided at 32. With further reference to the adapter it will be noted that it is provided on diametrically opposite sides with outstanding flanges (FIG. 2) which are denoted at 34 and which are bolted or otherwise secured to flanges 36 by fasteners 38.

As implied, the outboard motor is of a so-called conventional or generally welI-known-type and the power source is provided at the upper end and is appropriately encased or housed as denoted generally at 40. The shaft housing 23 encloses the power-driven shaft 412 (FIG. 3) whose lower end is geared or otherwise operatively connected with an appropriate bladed propeller 44. This propeller is of paramount significance in the overall concept and, broadly construed, constitutes the power driven booster means which increases the flow and circulation of water or other fluid through the conduit portion of the drain tile 14. The transom brackets, denoted generally at 46 are carried by the usual reinforcing sleeve 48 beneath the power source and in the instant situation they are suspended or supported on a horizontal brace 50 mounted between opposed sidewalls 52 of the aforementioned open-top boxlike well 54. This well is built of wood or the like and the walls 56 are within the confines of the pit walls 10 and have openings 58 to permit passage of the aforementioned portions 14 of the tile 16 therethrough.

It follows that the manhole-type embedded pit 6 encloses the coordinating built in boxlike well 54 and the walls of these two units serve to accommodate the portions 14 of the drain tile 16. The outboard motor 30 is insertable and removable and is substantially intact and is supported within the confines of the walls of the well 54. The brace :supports the structure so that the desired spinning propeller is, with the aid of the adapter means 26, properly located to achieve the boosting and circulating result desired. It follows that the disclosed invention well serves the purposes for which it has been evolved and produced. Accordingly, a more extended description is deemed to be unnecessary.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
